Welcome to the Santoianni blog!

Dawn Santoianni is an energy policy and communications expert with over 20 years experience producing scientific communications for industry, government and academia. Previously the owner of a small business consultancy that provided strategic communications support to the power industry, Dawn now works for a large energy company. This blog showcases geeky, interesting stuff on energy, physics and astronomy that I come across in my spare time.
